All Implemented Interfaces:

java.io.Serializable, javax.swing.table.TableModel

public class CropTableModel

extends javax.swing.table.AbstractTableModel

Table model for crop viewer. This is the model for delivering data to the crop table view. This handles loading the crop_defn.xml file and the crop_lang.xml file. The crop_defn.xml file contains the following information that is stored: - name of the parameter - type of the parameter, float, int, etc - default units for the value The crop_lang.xml file contains the following information that is stored: - long description of parameter, what is displayed as a column heading - an alternate unit (English) that the parameter can be displayed in - what to multiple the value by to display the value in alternate units - list of values and text for the choice lists that a parameter may have
